Hey, no problem, always happy to help. Exactly, it could well be a software problem. I was actually struggling with the brakes too, but since the mechanic looked over them, everything is running smoothly again. During my last visit to the workshop, it cost €955 to fix the sporadically faulty communication between the control units - no mean feat, but since then everything has been running smoothly again. So far there have been no further problems or difficulties. I hope that reassures you a little.

Thank you, that helps me. Good to know that it could also be a software problem. I will definitely insist that the mechanic checks everything thoroughly this time. I'll have to live with the repair costs, as long as there are no more problems afterwards. Thank you very much for your help, I really appreciate it, really cool of you. Let's hope that everything goes smoothly.

Hi, I actually had a similar problem with my 2017 Mercedes AMG GLE. The warning light also sporadically indicated faulty communication between the control units. The fault was not due to the brakes, but to a software problem between the various control units. I took the car to the workshop and they had to recalibrate the control units. This was a bit more complicated than just changing the brakes because all the systems have to communicate with each other. They then updated the software settings, which fixed the problem. It was a serious matter, as communication between the systems in the car is very important. If the connection doesn't work properly, the car can go out or other important functions can fail. So, on your next mechanic visit, I would suggest to check the software and communication issues between the ECUs and possibly update it. Hope that helps you.
